Purpose
Atomic nuclei studied through binding, structure, decay, reactions and collective behavior governed by strong, electromagnetic and weak interactions.

Entities → interactions → mechanisms → scales → measurement
Study nuclei as finite quantum many-body systems.
Nuclear physics connects microscopic interactions to bound states, decay and reactions across an energy range where multiple models remain useful.
Nuclear structure
Use shell, collective and other models to capture different regularities in finite many-body nuclei.
Radioactive decay
Study alpha, beta and gamma processes probabilistically through rates, selection rules and conservation laws.
Nuclear reactions
Track energy, momentum, angular momentum and quantum numbers through scattering, fission, fusion and capture.
Applications & environments
Connect nuclear processes to stars, reactors, medicine and detectors while keeping engineering and safety questions separate from fundamental physics.
Keep the boundaries visible.
These separations prevent nearby ideas from collapsing into one another before the subject is understood.
activity ≠ dose
binding energy ≠ activation barrier
half-life ≠ time when all nuclei decay
Questions that organize the Side.
Use these to test whether the model is becoming explanatory rather than merely familiar.
Why do several nuclear models remain useful instead of one universal picture?
Which conservation laws constrain possible decay and reaction channels?
How do nuclear reaction rates change across laboratory and astrophysical environments?
What should carry weight here?
Use decay spectra, scattering, mass measurements and reaction cross-sections, with detector response and model dependence included in uncertainty.
